The low point of the UAW's effort to organize Volkswagen's Chattanooga assembly plant was Sen. Bob Corker's bombshell on the first day of voting.

The Tennessee Republican said he was "assured" that if workers rejected the UAW, VW would provide a new product to build. He declined to name his source or sources.

VW immediately denied the claim. Frank Fischer, CEO of Volkswagen Chattanooga, said there was no connection between the vote and products for the plant. His response has the ring of truth because VW was neutral on the vote and let UAW representatives into the plant to campaign.
